Police in Derbyshire have started a month-long campaign to target drivers using mobile phones.

Drivers are being warned they face a £60 fine and three penalty points on their licence if they are found using a mobile phone while driving.

They also face a prison sentence if they are then involved in an accident.

Last year, a total of 1,800 drivers were caught and fined in Derbyshire for illegally using a phone whist driving, a police spokesman said.

Ch Insp Simon Kennedy, head of Derbyshire's road policing unit, said: "National research has shown that reaction times for drivers using a hand-held phone were nearly 50% worse than when driving under normal conditions."
